I've got an embedded system that uses a javascript-enabled browser as a
front end.
The input system consists of an encoder which generates + and - chars, and
a couple of keys that generate Tab and Shift-Tab for navigation.
Each field in the form is numerical, and has certain properties; for
example, one field represents %, and has a min of 0, a max of 100, and
increments of 1.
I need to come up with some javascript code that would take take those +
and - chars, and increment/decrement the field values so that the user can
'dial in' the value they need....

I need to make an HTML button whose value is "Times clicked: 0" and every time the user clicks it the value increments the number so it will say "Times clicked: 1" after clicked and so on. I don't know if a javascript function is the best way to do this, I know how to change the value on click but I don't know how to make it increment only the number
<INPUT NAME="myButton" TYPE="button" VALUE= " (I don't know what to put here) " onclick=increment()>
<script type="text/javascript">
function increment() {
document.myForm.myButton.value= (how do I make it increment?)
</script>

I'm kind of at a lose this is my first foray into using a multi-dimensional
array and I've run into a snag. for some reason the second dimension always
seems to end up being the last value of the second dimension of the array
ie: in the case below the conditionArray[[0][1]] always ends up being 6.0
where it should be 1.0. Code:

I'm having an issue determining whether the mouse is increment or decrementing.
Code JavaScript:
_self.mousedown(function(e) {
var initialValue = parseInt($('#value').val());
var initialMouse = e.pageX;
[Code]....
As I move my mouse to the right, this returns true. When I move the mouse to the left, this still returns true; because the currentMouse value is still greater than the initialMouse value.

Simply put, I need to take a variable (The number '20' in this case) that is displayed by an input box on my web page and plug it into a function so that whenever I click on a button, the number in the input box will decrease by 1.
Seems simple enough, though for hours I've been going at it with no luck. Skipping the rest of my code - I currently have:
<head>
<title> Online Slots </title>
<script type="text/javascript"
src="http://dave-reed.com/book/random.js">
[Code].....
The entire code is a slot machine project that's supposed to be extremely simple where you hit the button and it spins 3 wheels, 3 of the same image and you win. Every spin takes $1, every win gives $13.
The majority of the code is already working, however for some reason I appear to be failing badly at getting the read out to show a decrement of $1 every time you push the button.
I've tried so many different ideas that I've found across w3schools, webdevelopersnotes, dave-reed, ect - and so far I haven't been able to get any of them to work correctly.

Last evening I ran across this script which I think will address a need I have; replacing my radio buttons with images. The one difference I have is that I need to use a different button image for each of the 5 buttons in my group.Unfortunately, the script dose not apply unique classnames within the generated mark-up so if I'm to use this I need to apply some sort of counting variable that increments and use this variable to append the classname with.Around line 52/53 of jquery.checkbox.js is

/* Wrapping all passed elements */

My requirement: Each time a visitor arrives at a specific webpage i want the main image on the page to be different, or more specifically, one of 6 images which will be shown in rotation. Solution: Set a cookie. Each time the visitor access the page read the cookie and display the corresponding image. Then increment the value and rewrite the cookie, so that next time they'll see the next image in sequence. NB: if the cookie does not exist (first timer) or is at 6, then the value is set to zero (and then incremented).
Problem: Can't get my coding to work. Specifically it just doesn't do anything - no error message, no cookie written. I'm a very novice scripter, as in I've cobbled the coding together from bits off the net that i think i've managed to grasp some kind of an understanding of. Very suck it and see - so far lots of sucking and no seeing!

i have used it for creating a table with Sorting and Paging. The table works perfectly without any issues per se except what i need now. I have used the following files: jquery-1.3.2.js, JQtable.js, and jquery.tablesorter.pager.js.
My problem is that there are links in 1 column of the grid. If a user clicks on the link, the user is redirected to another page. But when the user clicks on Back button, the Jquery Table always loads on the 1st Page with default settings and does not load the page on which the row wa present.
i need to go back to the same page of the table (from where the link has been clicked) with the same size for paging and sort order on clicking Back or a Link to the Page.
So in short - is there any pugin which we can use witht the jquery table to save the state and use it to load the table accordingly on Page Load?

I have a page with a simple form: 3 hidden fields and 3 selects. I load the data for the first select via Ajax on domready. I have "change" event handlers for all 3 fields. If I select something in the first select, the corresponding data gets loaded into the second select via Ajax etc. So it's a "cascade" of selects. When an option in the 3rd select is being selected, I save the values of all 3 selected options in the hidden fields, and create a button for submitting the form. Until here everything works fine. When a users hits the submit button, he is being forwarded to a results page. Now, when the user hits the back button, and the page with the form gets loaded again, I check if the first hidden field has a value. If so, I try to fill all the form fields with the values the user had entered (i.e. the selections he made), which means I make 3 Ajax calls (to have all the data available), and mark the options the user had selected as selected. That works fine in FF 3 and 3.5, Safari 4, as well as IE 7 right now. IE 6 only display the data of the first select (as if the other two Ajax calls aren't successful or something - no errors though), while Opera 9 doesn't seem to remember the values of the 3 hidden fields (same issue with IE 8, but I'm using IE Tester, which is not always reliable). The html and jquery code (leaving out all the details) look like this:
<form id="myform" action="action.php" method="get">
<input name="manu_saved" id="manu_saved" type="hidden" />
<input name="series_saved" id="series_saved" type="hidden" />
<input name="type_saved" id="type_saved" type="hidden" />

I have a JSON data structure that I'm pulling in VIA an AJAX call. What I want to be able to do is click a button/link and be able to save this data structure to disk, but I'm not really sure how to go about this. I've been experimenting with the following:The link has the following format "<a href='data:application/json, " + data_structure + "'>Click here!</a>" I've been able to replace data_structure with text and /json to /rtf, which gives me a pop-up 'SaveAs' dialog box, and when I open the file, it has my text in there. However, if I do data_structure, I just get [Objectobject], which is telling me that I'm passing in the object, but that's basically it, I need to expand it out? I'm not really sure how to do that...Which leads me to calling a perl script. So I make an ajax call like so:
$.ajax({
'dataType': 'JSON',
'type': 'GET',
[code]....

I am currently working on a page that has a series of <div> tags that .show and .hide whencorrespondinglinks are clicked, the first <div> is visible when you load the page. When you leave the page and return to it, the page reloads and the the first <div> is visible. Is there any way for the browser to save the current <div> that is visible to stay visible when you return to the page?example of what I am trying to accomplish:I load a page and click on the third link to show the third <div> and then after leaving and returning to the page (by clicking the browsers back button) the third <div> is still visible, rather than returning to the original state of the page where the first <div> is visible.

I have to print my cell phone call records but unfortunately my wireless provider displays the number I called only when mouse is hovered over Call details. I have 470 call records and copy pasting all those numbers when mouse is hovered over it will be one hell of a task.
Is there any way I could save all the information related to Called Number and do not have to move my mouse for each and every number?
Using my basic programming understanding (Though I know nothing about java), they are using some mouseover function that displays this information. The possibility of this information to be on the server is less because this information is even available when I switch off my wireless.

Im using a plugin called select chain and modified it a bit. Right now im trying to pass only selected values of a multi select list through ajax. The following function does a bit more but im concerned with the part that says cust_val: customer.val().join(",") This should return only selected values. This is what happens if i put it in an alert(). however when i check firebug to see what was posted it shows the entire list. I've tried alternatives like option:selected.... they all work for aler() .. the info passed through ajax shows the entire list.
customer.selectChain({
target: market,
url: callback_url,
type: "POST",
data: { ajax: true, multsel: market_selects, cust_val:
customer.val().join(",") }
}).trigger('change');

I'm new to js/jquery and this forum so please forgive my potentially off-scope js/jquery remarks. I've been running a lot of toggles to show, hide, etc... divs and other HTML elements. It's making my application incredibly nice navigation wise.
Now to put myself in my users shoes. Say one user toggles on and off the things they want and don't want until they are satisfied with all the content of the screen. (That is by the way the nature of my application. A user loads in various variables via PHP and other means and when satisfied, a PDF is generated for them containing all their preferred content.)
Because: When a user is at a point where all the content they are viewing is worthy of a PDF, it is also worth saving that HTML 'view' (classes switched, variable adjusted, etc...). I would call it 'Save this workspace' or something along those lines.
I don't have a direct question per se but am more interested in the views of others who have similar thoughts and moreover, what relationship has jQuery had in helping employing some method?

I have a problem with cookies set via javascript. What I try to
achieve is, when a user comes on the intranet, he can click on a link (
a simple href) that will set the content to french or english. I want
to set a cookie to persist that choice each time the user comes back on
the intranet. This feature must be available everywhere on the
intranet and the link is placed in an inner asp script called Menu.asp
which is included each time a page loads.
Now, I know it's maybe not the best way to achieve this but I'm just
working from what has been made by others, I cannot change the way
things are made, too much work would be involved and they won't accept
to give time to do everything all over again.
The best approach I got was to set a querystring value and replace the
cookie value from vbscript code. The problem is, the intranet we have
use a lot of the querystrings for a lot of features and when I click
the English/French link, that info is lost. I've tried to set a
mechanism to keep all the querystring and only add a new value but I
got weird results...
So I've turned to Javascript and still got no luck... For some
reasons, the cookie gets deleted from the cookie file as soon as my
javascript modifies the cookie.
Here's an example:

WANT: Client to save an image to disk pressing a "download" button.
The image name is dynamic, from JS code on another part of the
page
DID: Read somewhere I can use document.execCommand("SaveAs") to do it
This solves it for MSIE, at least. My code is below
PROBLEM: What actually happens with MSIE is:
1) A window pops up promting me to save as.
2) The filename is correct, but the saveas type shown in the box is limited to "html" and "txt"
3) The "image" that is saved is not an image, but an HTML file containing the link to the image!! This is NOT what I want!
PLEASE help. How do I get MSIE to save the actual image instead?
PS With netscape, instead of the saveas dialogue, a window opens with
the image displayed. By clicking <CTRL-S> I can save the actual image.
